Abstract: Nowadays, Multimedia Communication has been improved rapidly to allow people to communicate via the Internet. However, Internet users cannot communicate with each other unless they use the same chatting applications since each chatting application uses certain signaling protocol to make the media call. The mapping architecture is a very critical issue since it solves the communication problems between any two protocols, as well as it enables people around the world to make a voice/video call even they use different chatting applications. Providing the interoperability between different signaling protocols and multimedia applications takes the advantages of more than one protocol. Many mapping architectures have been proposed to ease exchanging of the media between at least two users without facing any difficulties. However, the design of any of the existing mapping architectures has some weaknesses related to larger delay, time consuming, and security matters. The only way to overcome these problems is to propose an efficient protocol 1-protocol 2 mapping architecture. The proposed mapping architecture consists of protocol 1 domain (protocol 1 client, protocol 1 server, protocol 1-to-protocol 2 gateway), and protocol 2 domain (protocol 2 client, protocol 2 server, protocol 2-to-protocol 1 gateway). The tasks of the translation gateways are represented by the URI conversion, media capability exchange, translator of call setup and teardown signals, and real time media transmission
